Redundant Hardware Error Correction TRIZ Cases
- Resync Transfer Using Log Metafile for Storage Site Recovery
Logging virtual volume block number mappings into a log metafile allows parallel processing of data modifications, reducing resync time from hours to minutes.
- HMI Validation via Modified Indication Data Equivalence Check
Modifying indication data before equivalence checking detects processor failures without requiring separate validation programs.
- Memory Controller Data Restoration Mapping
A memory controller saves management data mapping program identifiers to volatile memory regions for precise data restoration after power loss.
- Control Apparatus Security State Assessment for Software Continuity
A control apparatus manages security and operational states of connected units to select a suitable target for software transfer during abnormal conditions.
- Messaging Server Notification for Cloud Disaster Recovery
A messaging server coordinates client receivers via middleware to reduce RTO and RPO during cloud failover.
- Fault-Tolerant Parallel Database Node Instantiation
A fault-tolerant parallel database system instantiates spare nodes to assume active roles upon failure detection.
